CENTURY ARMS CENTURION OPTIO-III

Tactical Power Meets AR-Style Familiarity

The Century Arms Centurion Optio-III brings the ergonomic comfort of the AR platform to the devastating power of a 12-gauge shotgun. Designed for shooters who want a seamless transition from their modern sporting rifle to a tactical smoothbore, the Optio-III is a gas-operated semi-automatic built for reliability, home defense, and range day dominance.

Why the Centurion Optio-III Stands Out
Equipped with a 20-inch barrel and a 3-inch chamber, this shotgun handles everything from target loads to heavy buckshot and slugs. In our full expert review, we found the Optio-III to be surprisingly lightweight at just over 7.5 lbs, making it easy to maneuver in tight spaces. The AR-style controls—including the safety, magazine release, and bolt lock—ensure that your muscle memory from the AR-15 translates perfectly here.

Key Features & Customization

• Adjustable Ergonomics: The fixed stock features an adjustable cheek riser, allowing you to get the perfect weld for iron sights or mounted optics.
• Modular Rail System: Short Picatinny rails at the 3 and 9 o'clock positions on the handguard make it easy to mount tactical lights or lasers.
• Familiar Sights: Features a removable A2-style carry handle with an integrated peep sight and a barrel-bolted front sight for a classic tactical profile.
• Versatile Capacity: Ships with a 5-round magazine and is compatible with most MKA-1919 style magazines and drums for those who need higher capacity.

Performance Tips for New Owners
To ensure the best experience out of the box, we recommend a "break-in" period using high-velocity shells (1,200 FPS or higher). While the gas system is robust, it performs best with quality buckshot or slugs during the first few boxes of ammo. Whether you are defending your home or clearing targets at the range, the Century Arms Centurion Optio-III offers a high-value, magazine-fed solution that won't break the bank.
